There are several possibilities I think.

- Either by defining an own image class like this:
I never tried but I guess you can inherit this class and overload the
functions you wish to extend.
- Create a script which adds those partitions during the first boot. I
did something similar to resize the rootfs:
- Use swupdate by stefano babic and create the partiion during
installation of the image. This is how we do it in the office.

You have to provide your own. I can not see any hooks to change the
layout. For me your request is very specific and could be hardly
handled by a generic approach.

You can check how they did it in the RPI

I would prefer to use swupdate. But I am unsure about dual bootimage support
